Question

Can u plz help me if not I understand but can u plz just give it a go

Answer 1

A. the ratio would be H2 over 1O

B. the ratio would be 10o over 20h

Explanation:

A. Because the water molecule is made of 2 Hydrogen and 1 Oxegen, then you would just put 2/1 or if she or he would like you to be more specific, 2h/ 1o.

B. For this one you would multiply by the 2/1 10 and put the denominator where the numerator is and the original numerator where the denominator used to be. Your answer would then be 10/20. Now you can simplify this ratio by splitting it in half and having it be 5/10 or better yet, 1/2.

I really hope this helps and if you need more explaining please let me know.

Answer 2

1:2

20:10

Explanation:

for every 2 hydrogen there is 1 oxygen.

20:10 for part 2 can be reduced down to 2:1 because there is still 2 hydrogen for every 1 oxygen
